OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 296,390, dated April 8, 1884.

Application filed Februar;v l, 1884. (No model.)

To @il whom t may concerne Be it known that I, ISAAC H. CONGDON, a citizen of the United States, residing at Onlaha, in the county of Douglas and State of N ebraska, have invented certain new and useful Improvements in OiLGups, of which the following is a specication, reference being had therein to the accompanying drawings, in Which- Figure l is an elevation of the oil-cup. Fig. 2 is a vertical section of the same on line a z of Fig. Fig. 3 is a cross-section on the line g/y oi' l. Fig. 4t is an elevation of the feed-stem detached from cup. Fig. 5 is a top View of Fig. et. Fig. Gis an elevation of the cap-nut detached from cup. Fig. 7 is a ver- 'tical section of the outer shell, with its hollow center stein shown in onepiece. Fig. 8 represents on an enlarged scale a cross-section of the feed-stem on the line :c x of Fig. 4.

The object of my improvement is to furnish au oil cup ci' simple construction, through which the dow of oil can be regulated from the finest to the coarsest, and also automatic and uniform after being set, and in which the cup can be refilled without d etaching its cylindrical top.

The invention will irst be described in connection with the drawings, and then loe pointed out in the claims.

In the drawings, A represents the feed-stem,

having its lower half cani-shaped in cross-section, and grooved longitudinally at a for the gradual passage of oil, and its upper end in the forni of a hollow cylinder, a2, with a projecting cap, c, resting upon the cylindrical upper end, l), of the cap-nut B, closing the top ofthe outer shell, (l. W'ithin the bottoni of the latter projects the hollow stein d, to guide the feed-stein A, and around the stem d is placed the glassJ shell E, and the latter is retained in position by ineans of a cork packing, g, placed upon its top edge, and a cork packing, It, under .the bottoni thereof. In the Walls of the shell low center or guide stem, d, is screwed into the outer shell, C, from the under side, and then leaded in or soldered, to prevent leakage. Said steni has a hole through the center, which is enlarged at the lower end for the reception of the spring f. A sinall hole, j, Fig. 2, is

drilled nearly horizontally into this central stem for the passage of oil to the groove a. In uniting the parts, the cork packing hv is first dropped into the outer shell, CQ The glass shell E is then put in, and is followed by the cork packing g. The cap-nut B is then screwed in place. This cap-nut B is a hexagon nut, having a cylindrical riin, Z1, project ing from the top of saine, through which is cut an oblong hole, K, Figs. l and 3, to receive the nozzle of au oil-can. An oblong hole, L, is cut through the hollow cylindrical part a2 of the feed-stein A, similar to the hole K in the upper part of cap-nut B. Then in place, the hollow cylinder a* of the feed-stem iits into the cylindrical upper end of cap-nut B, and the projecting stein A extends into and through guidesteni d. The spiral spring j' is slipped over the saine, and passes up into the enlarged hole in the lower end of the guide-stem d. The

end of the spring is passed through a hole I drilled through the lower end of the feed-stem A, and thus theprojecting cap e of feedsteni A is held close down on rim Z: of cap-nut B. A pin m, pendent from the cap a, has its lower end'pointed, and enters into pin-holes in the upper surface of cap-nut B. This point may be quite blunt, and the pin-holes deep enough, so that the pin will not bottom in same. A stop-pin, n, Figs. 3 and G, projects upwardly from the cap-nut B, in the circular path of the pin m, to arrest the latter at the end of its course. Then the flow of oil is closed, the pin m is then against stop-pin n, Fig. 3, and the groove a in feed-stein A is then away from the hole j in the. guide-stein d. 1When the feedstem A (having its lower half cam-shaped) is carried around so that the pin m is at O, Fig. 3, the groove c in feed-stem A is then opposite the holej in guide-stein d, and the feed is then full open. The flow is graduated to any required amount between the stop-pin n and the pin-hole O, by reason of the cani-shape groove in stern of feed-stein A. If feed-stem .A is -carried around so that the pin in is in pin-hole p, Fig. 3, the oblong hole K in the roo A cylindrical portion of Gap-nut B and the oblong hole L in the hollow cylinder a2 of feedstem A will be opposite one another, and

through these openings the eup aan be filled 5 with oil Without removing any of its parts. The small hole q through eap of feed-stem A may be necessary when the eup stands stationary to allow the pressure of atmosphere to force the oil 5 but When the eup is used on oonneeting-rods of engines, this hole is not put in, the motion of the eonneeting-rod being sufeient to eause oil to flow.

Having now fully described. my invention, what I claim as new, and desire to secure by 15 Letters Patent, is-

l. The Combination of the cam-shaped feedstem A and guide-stem d with spiral spring f, adapted to hold the cap of guidestem A close on top of the cylindrical Cap-nut B, substantially as and for the purpose set-forth.

2. The combination of the cani-shaped feedsteni A, having the cylindrical top o and oblong hole L, out through said cylindrical portion, with the cap-nut I3, having the oblong hole K, cut through the extended rim of the, 25 same, substantially as and for the purpose described.

In testimony Wh ereof I affix my signature in presence of tW Witnesses.
